Kurt Renzo Acosta · Answer

Have you referenced the generated `podspec` into the `Podfile`

romtsn · Answer

<https kotlinlang org docs reference native cocoapods html add a dependency between a kotlin pod with an xcode project with several targets> that is exactly how to include your kotlin lib as a pod to your xcode project

romtsn · Answer

and that is how the Podfile should look like roughly gt <https github com Kotlin multitarget xcode with kotlin cocoapods sample blob master severalTargetsXcodeProject Podfile>

romtsn · Answer

you also need to run `pod install` in the root folder where the Podfile is located and then try to build or clean build sometimes this works from the 2nd time building for me

aleksey.tomin · Answer

`pod install` works only in `severalTargetsXcodeProject` ```$ pod install Analyzing dependencies Downloading dependencies Generating Pods project Integrating client project Pod installation complete There is 1 dependency from the Podfile and 1 total pod installed The Podfile contains command line tool target s MacosCLI which are attempting to integrate dynamic frameworks or libraries This may not behave as expected because command line tools are usually distributed as a single binary and cannot contain their own dynamic dependencies ``` But it doesn t help

romtsn · Answer

check <https github com touchlab KaMPKit blob master docs TROUBLESHOOTING md|here> for me that worked out pretty well

aleksey.tomin · Answer

I ve removed `Pods ` run `pod install` and `xcodebuild scheme MacosCLI` The same problem

aleksey.tomin · Answer

I haven t opened Xcode

Liliia · Answer

< aleksey tomin> I m sorry there is one thing missed Gradle wrapper is necessary So when the project is ready please run `gradle wrapper` command before executing step 4 in your description Hope it helps

aleksey.tomin · Answer
